For the first time since the UK voted to leave the EU, government ministers have spoken publicly about energy and climate policies going forward.

As energy secretary Amber Rudd took to the stage at the Business and Climate summit in London, energy minister Andrea Leadsom appeared before a parliament select committee.

The two prominent politicians fought on opposite sides during the referendum debate, but were largely singing from the same hymn sheet: ‘It’s business as usual’.

Here are five things we learned.

1. Hinkley is happening, apparently

Despite “raising a host of questions for the energy sector”, Amber Rudd was adamant that the government’s energy commitments remain unchanged by Brexit, including on proposals to develop 18GW of new nuclear power stations at six sites.

The government will continue to go “full tilt” on plans to build Hinkley, the UK’s first nuclear power plant in a generation, Rudd added.

She confirmed that she has spoken to energy giant EDF, and that they told her that Brexit will not further delay their investment decision, expected in the autumn.

Rudd was strikingly passionate about the climate cause, and insisted that the UK would “not step back from international leadership” despite the ramifications of Thursday’s vote.

She refused to be drawn on who she would back for prime minister, but was adamant that a commitment to climate change would be “absolutely central” to the decision, a pledge that drew cheers from the audience.

“I will be very vocal” in holding them to account, she said.

And finally, she confirmed that the decision on the UK’s fifth carbon budget will be announced on June 30.

5. Rudd isn’t running

The Secretary of State, once mooted as a future favourite for the Tory top spot, revealed to the audience that she will not run to succeed David Cameron as Prime Minister.

Amber Rudd certainly not ruling out backing Boris this morning. Is she really going to endorse the man she said wasn't fit to drive home?!
